The D-D Dosing Tube Holder (DD-04 BPK) is a specialized accessory designed for precision-oriented reef keepers who utilize automated dosing systems. This compact holder eliminates common risks such as tubes falling out of the sump, back-siphoning, or chemical drips causing equipment corrosion. While "BPK" identifies the sleek black professional finish, the unit itself is engineered for heavy-duty daily use. It provides a secure and organized way to deliver essential supplements like Calcium, Alkalinity, and Trace Elements directly into high-flow areas of your filtration system.
The D-D Dosing Tube Holder ensures that your expensive reef supplements are delivered exactly where they are needed most.
Four-Channel Organization: Features four dedicated ports to hold standard 4/6mm dosing tubes firmly, allowing you to manage a full 4-part dosing regimen like Triton Core7 with ease.
Versatile Clamping Mount: Equipped with a robust thumb-screw clamp that securely attaches to the rim of your sump or aquarium glass, accommodating various glass thicknesses.
Anti-Siphon Design: By holding tubes securely above the water line, it helps prevent back-siphoning and ensures consistent volume delivery from your dosing pumps.
Chemical-Resistant Material: Constructed from high-grade, reef-safe plastics that will not degrade or leach toxins when exposed to concentrated reef supplements or saltwater spray.
Low-Profile Aesthetics: The minimalist black design helps maintain a clean, professional look in your equipment cabinet or sump area.
What size tubing does the DD-04 holder accept? It is specifically designed for standard 4/6mm (1/4") silicone or PVC dosing tubing, which is the standard size used by almost all aquarium dosing pumps (e.g., Kamoer, D-D, Red Sea).
Is BPK a brand or a product code? In this context, BPK is the brand
Can I mount this on a rimmed aquarium? The clamp is primarily designed for rimless glass sumps. If you have a plastic rim, ensure the jaw width of the clamp can accommodate the total thickness (typically up to 15mm–20mm).
Will the screws rust over time? The DD-04 uses high-quality plastic thumb screws, which are completely immune to the rust and corrosion that typically affects metal components in a saltwater environment.

D-D H2Ocean Dosing Tubing: High-quality, kink-resistant silicone tubing available in different colors to help you track your different chemical lines.
